I have configured a remote access VPN on my Firewall ASA5510. Everything worked fine and I can successfully connect through the VPN. The problem is I cannot ping or connect to any of my internal network resources. I tried to add a new NAT route from outside to my internal servers using the defined pool but due to a new ASA version there are many changed I see in the NAT routes
View 37 RepliesI've enabled antispoof on all interfaces on asa 5510.If you start a traceroute to a network on the default route, everything works, since replies comes to an interface with route 0.0.0.0/0 defined.If you start a tracer route to a network that is NOT on the default route (let's assume coporate MPLS), you only get response from first carrier router, the other are discarded because of anti spoof violation.
I have ICMP inspection and icmp-error inspection enabled.
I would like to route traffic that are coming in and going out to the same interface on ASA. I am using inside interface with security-level 100. In this URL, [URL], ASA is able to do that.

Don't want to do this through the site-to-site.I have temporarily added a few acl on the outside interfaces.when i traceroute it only goes one hop.. Maybe thats the way it suppose to be? I need to know all the hops between the outside interfaces on the 5505 to the outside interface on the 5510.

We configure the ASA in routed mode, we create the sub interface for server, client and dmz subnet and we connect the firewall ti the network. Everything works very good except the intervlan routin. If i try to send or receive a file in every protocol, ftp, http, smb o if i try to conne with rdp or vns to an host in a different vlan the connection goes very very slow. I particular a ftp connection between two host goes ti 15kb/s. I check all cable and port for some error on duplex ro speed, end all the uplink are 1gb and the single client connection 100Mb. I know that the main purpose of the ASA is not doing routing stuff but this behavior is very strange.

I have two links between my offices one for Data via a VPN and one for video traffic which is a secure connection with QOS end to end.
All interfaces are on the same security level of 100 except Outside which is 0.
Office 1 Interfaces ASA 5510
VLAN 1 vOffice1Data 10.40.1.0/24
VLAN 3 vOffice1Video 10.40.2.0/24
VLAN 5 vInterOffice 10.40.5.0/24 (QOS connection Between Offices)
[Code]....
At the moment if I try and access data from VLAN 1 to VLAN 4 it gets to the destination ok going through the static route and over the vInterOffice connection but the problem is VLAN 4 returning the traffic. This fails because there is no static route back to VLAN 1. If I create a static route from Office 2 to VLAN 1 then it will route all my data traffic over it as well.
I am trying to set up my ASA5510 the fail over of ISP when it can't ping three different IP. I create three different tracking to three different IP using sla monitor & track rtr. But when I do
route isp2 0 0 yy.yy.yy.yy 50
route isp1 0 0 xx.xx.xx.xx 31 track 1
route isp1 0 0 xx.xx.xx.xx 32 track 2
route isp1 0 0 xx.xx.xx.xx 33 track 3
the last route will replace the previous two and only the last route command takes effect.Is there anyway I can set up the fail over to ISP2 only when it can't ping three different IP from ISP1?
I recently added a business cable modem to relieve some of the congestion I was getting on my T1 for our MPLS network. There was an ASA 5510 collecting dust in a closet here and I thought it would be the perfect device for firewalling the traffic coming in from the Cable modem, and handling the routing of our internal MPLS traffic as well. Internet setup was cake. The test laptop I have using the ASA as it's gateway has great internet service but it cannot ping across either of our MPLS networks. I have one MPLS with AT&T and one MPLS with EarthLink. My hope was to use the cable modem as the Default route for all unspecified internet traffic and route our internal MPLS traffic to the cisco 2800 routers that are currently in place for the MPLS. I can ping across the MPLS when I telnet to the ASA, but I cannot ping across the MPLS from the client that is connected to the ASA.
Here's the topology I'm working with

I am having touble with a NAT concept. What I have is a 3rd party software VPN product that basically tunnels encapsulated traffic to/from a server sitting inside the network. Right now this traffic utiluizes a physical interface on the ASA5510, but I need the interface for another project.

I have a cisco ASA 5510 that I have set up currently to access via ASDM through the Inside interface. When I VPN in using our older VPN server I can connect to it fine. I recently set up the ASA to also be a VPN server which will eventually replace the older server for our HQ. I noticed that when I'm VPN using the ASA as the VPN server, I can only ASDM to the public which I prefer not to allow. Access to the inside doesn't seem to work this way. What configurations if any would be causing this. I'm assuming it's some thing I need to adjust in the VPN configuration.

View 1 Replies View RelatedI have a Cisco ASA 5510 that was set up as a VPN server for working remote. I have disabled split tunneling so that all traffic created while VPN'd in goes through the ASA. The problem I'm having I believe would be resolved if I enabled split tunneling but I would prefer another solution. Now..for the problem.When a user is connected via VPN, they can hit all intended devices both public and private accept servers that have static NATs in the FW. So Server A has a public of 1.1.1.1 which is one to one mapped to private address of 10.1.1.1. Now if the remote user brings up a browser and goes to 1.1.1.1 it wont work. The FW gives me a error which is posted below. However, using the private IP of the server works. I thought about trying to manipulate DNS to resolve this as the remote users are using URLs and not IPs when trying to reach these servers but again, was hoping I could resolve the NAT problem that the FW seems to be having.
Asymmetric NAT rules matched for forward and reverse flows; Connection for tcp src Outside:192.168.202.100/49238 dst INSIDE:1.1.1.1/80 denied due to NAT reverse path failure 192.168.202.x/24 is the remote vpn ip given via the ASA.
Here are some configurations on the ASA:
static (INSIDE,Outside) 1.1.1.1 10.1.1.1 netmask 255.255.255.255
access-list INSIDE_nat0_outbound extended permit ip object-group DM_INLINE_NETWORK_2 192.168.202.0 255.255.255.0

Outside with 4.4.4.4 as the public ip traffic gets NAT'd do dynamically Inside with 10.1.1.x network on it.The ASA is running 8.2

View 1 Replies View RelatedASA 5510 ASA 8.0 ASDM 6.1 I want some remote users to have split-tunnel connection, others not. I used Cisco Document ID 100936 "Allow Split Tunneling for AnyConnect VPN Client on the ASA Configuration...". I created a new Group Policy with split-tunnel enabled. I created a new Connection Profile and assigned to it the new Group Policy. When I authenticate at the AnyConnect client I get a dropdown of the 2 connecton profiles, to choose the one I want. Each of them works, enabling or disabling split-tunnel. But I want to assign a connection profile to the particular user, not give the user a choice. The problem is I'm using LDAP authentication. The Local Users I set up before LDAP are obsolete, assigning them a Group Policy does nothing. I really don't want to give up LDAP and force people back to another local password. But the LDAP authentication to Active Directory just says yes or no, it won't assign a connection profile. At the AnyConnect Connection Profiles page I have set a switch "Allow user to select connection profile, identified by its alias, on the login page. Otherwise, DefaultWebVPNGroup will be the connection profile". If I clear that switch every user will be assigned the same default profile, which does not work.

I have a customer which has a main location office and a remote one. Recently we interconnect their facilities using a local ISP service called Virtual Connectivity, which basically is a private network which can be accessed over aDSL or any other data circuit. They are using Cisco 888 routers to interconnect both sites.At the main site the customer also has an Internet circuit (with a Cisco 857 router)and he wants to remove the Internet circtuit from the remote site and provide them access over their main location Internet circuit.At the primary offices, we installed Cisco 2811 router as a gateway to route the Internet and remote network traffic over the required data circuit. Everything is working fine, but we can not access Internet from the remote location over the circuit installed a the main site. I understand this is a routing issue, since the traffic hits the main office network it does not knows how to reach the Internet. I am assuming this routing must be set into the main office Cisco 888 router (installed by the ISP to interconnect to their private cloud) in order to properly route it over the Internet circuit.Since I already have access over the Internet router and the gateway router at the main site, but not into the ISP router, is there any other way I can make this configurtion over the routers I already have access?
View 3 Replies View RelatedI have been endlessly searching around online, and trying things on the firewall, and cant seem to find an answer to this problem. Its probably something really simple right under my nose! I am using an ASA 5510, which currently has a few seperate site-to-site VPN connections configured, which connect to other Cisco devices on clients networks.
I work from home, so also connect to our network using Remote Access VPN (any connect) to connect to the network at the data centre.
Just to be clear, here is my amazingly drawn network diagram:
[[my house]]-------------- <any connect VPN>------------[[ASA 5510 / Data centre]]-----------<site-to-site>-----------------[[Client network]]
The problem I am having, is that I cannot connect directly from my house to the client network, I need to RDP into some server in the data center, then from there I can see the Clients network. Is there routing to be setup somewhere? between VPN's? Ive looked into the routing options on the firewall and cant seem to find anything that works. I've searched for this and cant find answers, even some sources saying its impossible.
I am having a strange requirement. actually I am not sure it is strange or not. I am having ASA5510 with 8.4 sw version. Currently one ISP is connected to it. It is working fine. We have some servers that are directly connected to internet using another ISP connection. These servers having public IP addresses configured on their LAN settings. I need to move these servers in to the DMZ zone.
When i connect it to the ASA's DMZ zone,servers will get internet through the first ISP that is already configured on ASA. But i need to NAT the DMZ servers with the IP address provided by the other ISP, which even not configured on ASA.
So what should i do? In short my requirement is
1) need to NAT the server with the IP address provided by another ISP
2) Also note that the default route is configured for the first ISP only in ASA
so Do i need to configure another default route? Do i need to make it with larger AD? So i do it will act as the secondary route only.
I need to make the ASA up and running for two ISP, and servers in the LAN should be able to NAT with the IPs of first ISP and ,the servers in the DMZ zone should be able to NAT with the public IP of the new ISP.
I have an ASa 5510 and setup remote dial in users.
I wanted to use the windows 7 built in client and also the draytek site to site VPN options however when they connect VPN traffic will not work however when i use the cisco VPN client then everything works fine.

My setup has two firewalls to the internet, one is for all internal users who want to access the internet and the other is an ASA5510 acting as VPN terminaton to remote workers accessing using Anyconnect.
Each of the firewalls has a public interface on the same network (ex. 196.160.100.192/26).
We have a server with a public interface, and all traffic (internal and external) has to access via the public ip (again in the same network as above) and there are different profiles and access levels on that server depending if you are accessing from an internal IP or a public IP.
Well, when users are connected thrugh the VPN, although they have an internal IP address, as they are accessing the server on the public IP, the ASA sends the packets through its external interface (direct connected route) instead of sending it to the default internal gateway that is a "trusted" entry point on the server.
Any way to force the ASA to send that traffic to the internal default gateway instead of sending it to the external (direct connected) interface?
I have no access to the server (appliance under warranty) so I can't make any changes to it...
Firewall: ASA 5510

Switch Setup:
I've been tasked with breaking up a network that has run out of IP's, and have decided to use VLANs to accomplish this. I have to use an ASA5510 to accomplish all the routing between hosts in different VLANs.Port 48 is trunked to the ASA eth0/0 interface, with VLAN 99 and VLAN 20 tagging packets, VLAN 1 Untagged. Hosts hooked up to appropriate ports on Switch.
I am a complete newbie to Cisco equipment. So far I've been able to figure out how to do most of what I needed by using the ASDM but I have run into something that is a little more complicated that just opening a port. We currently have a connection to our remote site. This site has a T1 internet connection. Our connection is a site to site VPN with an ASA-5510 on this end and a ASA-5505 on the other.
We are upgrading this connection to a 75mbit hybrid microwave/fiber link. The provider is going to hand it off to us as an untagged VLAN. We made the decision to route all of the remote site's internet access through this location as to avoid having to split off part of the bandwidth of this link to dedicate to internet access.........
We are deploying a new office in the building next to our main office. The main office has a Cisco ASA 5510 behind that is a Cisco 3750 stack. In the new office we are deploying a new Cisco 3750, they will be connected via fiber cable. I have sliced off VLAN 800 as a transit link /30 with an address space of 10.249.249.1-4. The new 3750 only has two VLAN's 800 and 112 (10.112.0.0/24). VLAN 112 routes are advertised to the neighboring 3750 properly as seen in the routing tables of the 3750 stack:
D 10.112.0.0/24 [90/3072] via 10.249.249.2, 00:22:24, Vlan800
Traffic passes between all local VLANS with no issue. I found in order to get packets to pass between the ASA and the new 3750 I had to add a static route to the ASA:
S 10.112.0.0 255.255.255.0 [1/0] via 10.100.0.1, inside
My question is why is EIGRP not advertising the 10.112.0.0 network to the ASA. Here are EIGRP configs on the switches
